Optionally, the mirror finish can use the machining mode for removing material, such as grinding or polishing etc.；Can also Using the machining without cutting rolling mode of minute surface instrument；The surface of first area 101 after mirror finish is due to thick Rugosity is relatively low and finish is higher, has mirror effect.
S112：Spark line is formed on the surface of second area 102 by electrode spark discharge.
Optionally, the surface of the high pressure thawing second area 102 of moment, the table of second area 102 are produced using spark machine Face produces rugged lines in the presence of instantaneous pressure electric shock, you can spark line is formed, to cause second area 102 Surface there is spark line.
Optionally, the scope of the VDI3400 standards of spark line is 18~30.
S12：By first time be surface-treated after mold injection molding with obtain having corresponding smooth domain surface and The matrix of spark line region surface；
Optionally, makrolon or polymethyl methacrylate material can be selected at the subsurfaces of above-mentioned steps S11 first To form the matrix of predetermined shape, an inner surface of the mould after being surface-treated due to first time is had for injection in mould after reason Smooth first area surface and the second area surface of spark line, therefore after moulding, an appearance mask of the matrix There are smooth domain surface corresponding with the second area surface on smooth first area surface and spark line and fiery pattern area table Face.
S13：Second of surface treatment is carried out to the surface of matrix, to cause smooth domain surface and spark line region surface There is the first metal-like and the second metal-like respectively.
Refering to Fig. 4, step S13 may particularly include:
S131:Decontamination processing is carried out to the surface of matrix；
Optionally, supersonic wave decontamination cleaning is carried out to the surface of matrix using supersonic wave cleaning machine, ultrasonic wave is a kind of frequency Rate exceeds more than human hearing range 20kHz sound wave, and the propagation of ultrasonic wave will rely on elastic fluid, when it is propagated, makes elasticity Particle oscillation in medium, and energy is transmitted by the direction of propagation of ultrasonic wave by medium, this ripple can be divided into longitudinal wave and horizontal stroke Xiang Bo, in solid, both it can transmit, and in gas and liquid, only longitudinal wave can transmit.Ultrasonic wave can draw Play particle vibration, the acceleration of particle vibration and supersonic frequency it is square directly proportional.Therefore, the ultrasonic wave of several KHzs can produce Great active force, when intense ultrasonic wave is propagated in a liquid, due to nonlinear interaction, acoustic cavitation can be produced.Dashed forward in cavitation bubble The shock wave so sent during closure can produce thousands of individual atmospheric pressures around it, on the one hand broken to the direct repeated stock of pollution layer The absorption of bad dirt and cleaning parts surface, on the other hand it can also cause the destruction of crud layer and depart from cleaning parts surface and make them It is distributed in cleaning fluid, the vibration of bubble can also be cleaned to the surface of solids, and bubble, which " can also pierce " in crack to do, to be vibrated, and is made Dirt comes off.
After the washing, using dry cloth by the matrix wiped clean after cleaning, and in wiping process, it is impossible to use isopropyl The chemical agent such as alcohol or tincture ketone is wiped.
S132：Matrix after decontamination processing is carried out successively in UV basecoat paints, non-conductive vacuum plated film, UV paint spraying and UV finish paints are sprayed to form prime coat, film plating layer, middle enamelled coating and top coat layer respectively.
Matrix surface first after cleaning carries out UV basecoat paints and forms prime coat to improve follow-up middle vacuum coating Brightness and adhesive force, optionally, wet shot is carried out using spray gun, UV bakings are carried out after wet shot, baking temperature is 75~85 DEG C, is dried The roasting time is 6~7min, and UV energy is 700~800mj/cm2。
Optionally, the thickness of prime coat is 2~3 μm.
Then film plating layer is formed using non-conductive vacuum coating process, optionally, the thickness of film plating layer is 20~25nm, plating Membrane material is indium or indium stannum alloy, plays imitative metal effect.
Enamelled coating to film plating layer to play a protective role during further paint spraying is formed in progress UV, optionally, middle enamelled coating Thickness is 6~7 μm, and baking temperature is 75~85 DEG C, and baking time is 6~7min, and UV energy is 400~500mj/cm2, spray painting Material selection light color based material, to improve the mute contrast effect of light.
Finally carry out UV finish paints to spray to form top coat layer to play a protective role and abrasion resistant effect, and different light can be realized Damp demand, optionally, the thickness of top coat layer is 20~25 μm, and the mute degree of light is more than 8 light splitting, and baking temperature is 75~85 DEG C, baking Time is 6~7min, and UV energy is 800~1000mj/cm2。。
In decontamination, UV basecoat paints, non-conductive vacuum plated film, UV are carried out on the surface of matrix by step S13 After paint spraying and the spraying of UV finish paints, metal-like can be achieved in the surface of matrix, is wrapped in conjunction with the surface of matrix in step S12 Include smooth domain surface and spark line region surface so that smooth domain surface has the first metal-like, fiery pattern area table Face has the second metal-like, and then make it that on the surface of matrix two kinds of metal-likes can be realized simultaneously.
The housing embodiments of mobile terminal provided by the invention are prepared using the above method, specifically see above-mentioned reality Example is applied, will not be repeated here.
